'The pair have reared three generations of adopted flamingos, by making off with the freshly laid eggs of their heterosexual neighbours. ... They have been known to fight the heterosexual birds and steal their eggs. There is usually a 'handbags-at-10 yards' moment where they scrap with the couple before stealing the egg.' (news.telegraph)
while straight flamingos usually find a new partner every year, carlos and fernando have been together more than five years.
